Got some food for the CNC.. Couple of large chunk of Elm, and some Ash. I'll thickness it with the CNC itself, and have a closer look at the grain, so far it looks quite good...

OpenJSCAD Debug Modifier?
I'm starting with openjscad, with the intention of perhaps making a CAM set of tools, as there's already pretty much everything to do in in the JSCad libs..
Now, in OpenSCAD theres the '#' and '%' modifiers to see bits of geometry, even if they are part of the contruction of a bigger object; is there an equivalent in JSCAD?

Not every day that I can post #guitar p0rn AND #cnc  p0rn in one post! :-)
Here is the first 'serious' CNC job, I wanted a clear Plex pickguard for the Brunette telecaster I built over xmas, so I scanned the one I had, traced it in Inkscape, and cut a new one on the CNC.
I flamed cleared it (altho the cut were very clean) and it's a perfect fit.

Thing is, what actually drove me to build the CNC in the first place is likely to be the fact I couldn't get a pick-guard /just like that/ -- so it's the most expensive and complicated DIY pickguard, ever :-)

Cool. I loved cutting out the pick guards for a few guitars. Dont rely on that huge bevel bit for engraving. Get tiny carbide cutters for that.

Thats more or less how I assembled my Z BTW, it made immediate sense not to tighten the delrin until the rest had been properly aligned, and yes, it's not at all how the video lists the operations.
Also, for the same reason, it's important to tighten and adjust the whole Z wheels assemblies before you do that, and try to make sure that wheel pressure is as constant as possibly on the 3 wheel sets, so make sure there's isn't any 'twist' on the leadscrew. 
Continuing from Part 2. After getting things together up to the end of Part 2, I think that things should be assembled in a slightly different order. I didn't tighten the screws down on my delrin nut because I wanted to do it...

There, CNC is about as ready as it'll get before serious chips start happening. Obviously the back and electronics need cleaning up, but that's enough there to make it do real work.
Filtering is very likely to be sorted too, it will still need to be proven tho. Lazor was since aligned and it has no parallax. Perfect! :-)

Today is the day I no longer use a Mac. After using a mac for more than 30 years, and having been a Mac developer for most of my life, today I retired my 2008 Mac Pro after a long, and problem free life. Best computer chassis ever made, but now, it's a bit long in the tooth, the graphic card especially can't drive my new fancy 4K displays, so...

It is replaced by.. a hackintosh. I can make about 3 top of the range hackintosh for the price of a single "ashtray" Mac Pro so hey, it's not like I'm saving Apple from bankruptcy like I felt I was in the 1990's.

New machine is Intel 5930K (overclocked to 4.4Ghz) 6 cores, 32GB DDR4, SSD, nice chassis and GTX 750 nVidia. Chassis is Fractal Design R5. Not as pretty, and not as heavy as the old mac, but still pretty good hardware, runs silent, and runs /circles/ around the poor old mac.

There, a new age begins. Apart from photography (Lightroom), I no longer really 'need' a mac, and the last few OSX revisions have been getting worse and worse; it's sort of pathetic really. Anyway, perhaps in 5 years time I will have found alternatives to my mac needs and will leave it all behind...

I understand your feelings. I grew up with Macs before ever using a PC. But Apple have just got too big for themselves recently, and really don't offer much new or value for money.

Nice PC build by the way!

Going into oak like it's butter with the #CNC.
Using a 2 flute chinese 3mm bit. The toolpath is not very good, I made it with Sketchucam, as yet another tryout of a CAM tool I'm satisfied with...

pretty cool gizmo. ebuyer gives away a 64GB class 10 card with the 1TB model too
 
As an alternative battery powered Mini PC capable of running Linux I'm now using a WD My Passport Wireless mobile storage device running Debian with LXDE.

The device comes with a "500GB" HDD which is partitioned with a visible 496GB HPFS/NTFS/exFAT file system and a hidden 4.3GB file system which I assume is used for recovery / factory resets.  It also supports an SD card.  The actual configured OS is a Buildroot Linux (version 3.2) installed on a UBIFS on eMMC along with the bootloader etc.

But the exciting part is the 2x2 MIMO Wi-Fi Module meaning both wifi network connectivity together with a wifi access point. And as the CPU shows as a ' am335xevm' or AM335x Evaluation Module which is a Sitara AM335x ARM Cortex-A8 CPU one can run Linux from 'chroot' environment using a previously created ARM root file system.

Because the installed OS doesn't support the 'ext4' file system I initially took one of my ARM RFS images and rebuilt it on 'ext3'.  I could then run this directly as a mounted image or by copying it to the (effectively unused) hidden partition.  I can also run a 'chroot' environment by copying the RFS to an SD card partition.  Also as the CPU / memory configuration is very similar to the Beaglebone Black I can also use the various images provided for that board.

Here's a video of accessing the WD My Passport Wireless from a Windows PC (MINIX Neo Z64W) and running a Debian 'chroot' ... see https://youtu.be/1noXmiHLqt4 ... I've also added pictures showing accessing the device from an Android Nexus 4 phone and running various Linux flavours (Debian, Ubuntu, Xubuntu) or running Linux from the command line together with a picture showing access from a Nexus 5 and using the internet via a web browser on Debian.  

Although running Linux with a GUI on a phone might only be suitable for a party trick, I've found using the CLI very useful in writing code and shell scripts whilst on the move.
